The HCSL output swings 700–900 mV peak-to-peak into a 50-Ω terminated differential pair, matching the input requirements of most PCIe clock buffers and PHYs without external level shifting. Supply voltage range of 2.25V to 3.6V covers both 2.5V and 3.3V rails, so the same part can serve multiple voltage domains on the board — useful when consolidating BOM lines across a multi-rail design. The 6-SMD no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a compact footprint that fits tight card-edge placements or mezzanine boards where vertical clearance is limited. ## Enable/Disable and power budget Active supply current is 42 mA max; disabling the output drops it to 22 mA max — a 20 mA saving per oscillator that adds up on multi-lane designs with several reference clocks. ## Active lifecycle – sourcing posture","metaTitle":"DSC1124CI2-200.0000T – Microchip 200 MHz HCSL MEMS XO","metaDescription":"Microchip DSC1124CI2-200.0000T: 200 MHz HCSL MEMS oscillator, ±25 ppm, -40°C to 85°C, 6-SMD.

When disabled, the oscillator stops switching and the supply current drops from 42 mA max to 22 mA max.
